S'Claims. (01. 285-22) This invention relates to means for facilitatingthe removal and replacing of valve means of an underground storage tankso that the parts can beinspectedand repaired very easily and withoutdigging up the tank and with means for holding the parts in liquid-tightengagement while they are in operative position.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to'behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference '15 will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which: Figure 1is a view partly in section and partly in elevation showing a tubularconnection between an underground tank and a manhole cylinder with theinvention applied thereto.

Figure 2 is a section ontthe line 2- -2 of Figure 1.

Figure 3 is a section on the line 3-3 of Figure 1.

Figure 4 is a section on the line 4-4 of Figure 1.

Figure 5 is a section on the line 5-5 of Figure 1.

Figure 6 is an elevational view somewhat similar to Figure 1 but showinga modification.

Figure '7 is a section on the line 1-1 of Figure 6.

In these drawings the numeral I indicates a portion of an undergroundtank, such as used for gasoline and the numeral 2 indicates an elongatedvertically arranged tubular member which has its lower end reduced andconnected by a tubular coupling 3 with the top of the tank. At the upperend the member 2 is provided with a cap 4 which is threaded thereto andthis upper end of the member 2 fits in a manhole cylinder 5, the top ofwhich is closed by a cap 6 which is formed with a cylindrical part I thebottom of which has a hole 8 therein for receiving the stud 9 on the topof the cap I, this stud having a hole therein for receiving a lockingbolt I0 so that the cap I cannot be removed by unauthorized persons, itbeing necessary to remove the lock Ill before the cap 6 can be removed,so as to expose the cap I. The cap 6 is closed by a cover plate I I.

A vertically arranged tube I2 extends from a point adjacent the bottomof the tank I into the ,5 lower part of the tubular member 2 and has atits lower end the usual foot valve I3. 'A casing I4 has a dependingtubular part I5 into which the upper end of the pipe or tube I2 isthreaded. The member 2 at one side is formed with a fiat laterallyextending part It whichhas the openings I7 therein, the outer ends ofwhich are threaded to receive the pipes I8 which lead to the servicepumps. A valve arrangement shown generally at I9 is located in the innerend of each opening I! the valve 20 of which is closed inwardly by theaction of the spring 2i, suitable .gasketslz being provided for theplates or spiders which carry the valve means. The casing H1 at one sidethereof is formed with the lateral openings 24 for registering with theinner ends .of the openings I7 and this side is practically fiat andvertical as shown at 26 to bear against the inner portion of the fiatpart I-6 and portions of the casing I4 around the openings 24 thereinbear against the gaskets to form a from one point toward the part I6 andthey terminate in vertically arranged hook-shaped portions 33 which arelocated one at each side of the part I5 of the casing I4 when saidcasing I4 is in position.

Thus by moving the lever 29 with the casing I4 suspended on the pin 21downwardly into the part 2 its pins or trunnions 30 will strike thesloping shoulders 3| and these shoulders will direct the pins downwardlyand forwardly until they engage the spaces formed by the hooks 33 andthis will place the casing I4 close to the part I6. Then by swinging thetop of the lever to the right in Figure 2 the casing I 4 will be forcedtightly against the gaskets 22 at the inner end of the member I6.

The upper end of the lever 29 is held in the position shown by having athreaded shank 35 formed on a ring-shaped part 36 passed between theforked upper end of the lever with the nut 31 on the shank 35 forforcing the upper end of the lever to the right or toward that side ofthe member 2 which carries the part It. When this is done the ringmember 36 which is of split and spring construction will engage aportion of the 2 gaze te member 2, as shown in dotted lines in Figure 4so that the lever 29 is held in position exerting pressure on the casingII to hold the same in nected with the storage tank by a single footvalve and the valve arrangement shown at 19* will enable one pump :to beused while .thegasoline is held in the line leading to the other pum'pand when it is desired to inspect or repair the valve the nut 31 isloosened on the shank and Q then the lever 29 is moved to the leftinFigure 2 and this pulls the casing l4 fromthe part 16 and a then thelever is raised which will raise the easing It the tube l2 and the footvalve and the valve assemblies 19 are exposed, and, can be reachedthrough the: member 2 when caps I and 6 are removed. I

Figures 6 and 7 show an arrangementsubstantially similar to that beforedescribedexcepting that the member l6 has a single opening therein forreceiving a supply line for a single pump and, of course, the casing I4,is made in the form of an elbow with a single passage therethrough forconnecting the pipe l2 having the foot valve at its bottom with thenipple or member [6' when the lever 29'is moved totthe right in Figure7. In other respects this form of the invention is similar to thatbefore described.

A nipple 3 may be connected with the coupling 3 so that a supply pipecan be connected with the coupling. r

It is thought from, the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangementof the several parts provided thatsuch changes fall within the scope of th appended claims.

Having described the invention, what is claimed as new is: v i

1. In a device of the class described, a tubular member having a partprovided with outlet means, a casing within the tubular member having aflat part for engaging the innerend of thefirst-mentioned part, afulcrum lever pivotally connected with the casing, a fulcrum formingpart in the tubular member below the casing for receiving a lower partof the lever guiding means for engaging a part of the fulcrum lever forguiding the same to the fulcrum forming part of the tubularmember and toa point where the casing is engagedj with the first-mentioned part, andadjustable'means connected with the upper end of the lever and engagingan upper part of the tubular memberfor holding the lever in positionwith the casing pressed tightly against the first-men- ,tinned;:part.,;V i

'; p2; In a :device of the class described, a tubular memberhaving athickened part provided with outlet jmeans, a casing having a part forengaging the inner end of the thickened part, a fulcrum lever having ayoke at its lower end, a pin connecting the casing with the lever,recessed parts on the internal walls of the tubular member underthecasing, pins on the forked part of the lever for engaging the recesses,guiding shoulders on the internal walls of the tubular part for guidingthe pinsfof theylever into the recesses and means at:the upper end ofthe lever for holding the same .in positionwith the casing pressedtightly against the :inner end of the thickened part.
